What cell organelle does photosynthesis take place in?

The chloroplast is the cell organelle that photosynthesis takes place in.

What discirbes chlorophyll breaking down into new substances?

Chlorophyll breaking down can result in the formation of colorless compounds like phyllobilins, which give different plants their fall colors. This breakdown process usually occurs as plants prepare for winter or when leaves senesce.

What happens chemically when chlorophyll absorbs light energy?

When chlorophyll absorbs light, much of the energy is transferred directly to electrons in the chlorophyll molecule, raising the energy levels of these electrons. These high-energy electrons make photosynthesis work

What do plants need to go through photosynthesis?

Plants need sunlight, carbon dioxide, and water to go through photosynthesis. They use sunlight as a source of energy to convert carbon dioxide and water into glucose, a type of sugar that serves as a source of energy for the plant. Oxygen is also produced as a byproduct of this process.

What organelles are found only in animal Cells?

centrioles. during mitosis in animal centrioles are used for division to create spindle fibers to move and connect the chromosomes/chromatids. In plants the spindles are all ready in the cell and do not need to be produced so no centrioles are necessary.

What is the function of some enzymes is a seed during germination?

A seed contains an embryo plant. it also contain a food store on which the embryo will rely while it is germinating, until it has grown leafs and can start to photosynthesise. For example bean seeds contains a lot of starch. Starch is insoluble. When the seeds begins to germinate, the enzymes amylase is secreted. This breaks the starch into maltose, which is soluble. The maltose can then be absorbed by the growing embryo, which can break it down to glucose. The seedling can then use it to supply energy for growth, and also to build up cellulose to make up cells walls for the new cells that are made as the seeding grows

How does respiration occur?

when the air pressure outside the body is greater than the air pressure inside the lungs, the lungs fill with air (simple physics). when the alveoli absorb the oxygen and transport the oxygen through the capillaries to the red blood cells, all that's left of the air is carbon dioxide, and probably some nitrogen. the diaphragm (muscle below the lungs) then contracts, forcing whats left of the air out of the lungs, and the entire process repeats itself.there are 4 or more usally. respiration is also the pressure air point. please people do ur own homework.

Where in the leaf does photosynthesis occur?

Photosynthesis occurs in the chloroplasts of plant cells, specifically within the green pigment chlorophyll. Chlorophyll absorbs light energy and converts it into chemical energy through a series of reactions that take place in the chloroplasts.

What are products of photosynthesis?

Energy (ATP)

Carbon Dioxide

Water (H2O)

You're Welcome =}

glucose&oxygen.

What is the edges of papaya leaf and shape?

Papaya leaves have smooth edges and are typically palmately lobed, meaning they have multiple lobes originating from a single point like the fingers of a hand.

How does the process of the photosynthesis work?

Photosynthesis is a process used by plants, algae, and some bacteria to convert sunlight, carbon dioxide, and water into glucose (sugar) and oxygen. This process takes place in the chloroplasts of plant cells and involves two main stages: the light-dependent reactions, where sunlight is used to split water molecules and produce ATP and NADPH, and the light-independent reactions (Calvin cycle), where ATP and NADPH are used to convert carbon dioxide into glucose.

Are photosynthetic pigments lipids?

No, photosynthetic pigments such as chlorophyll are not lipids. They are organic compounds that absorb light energy for photosynthesis in plants. Lipids are a separate class of biomolecules that include fats, oils, and phospholipids.

Why does glucose yield up to 38 ATP in cellular respiration but only takes 18 ATP and 6 nadph to synthesize during photosynthesis?

ATP and ADP are energy molecules (adenosine triphosphate and adenosine diphosphate, respectively). In ATP there are 3 phosphate groups, hence triphosphate. When you break off one of those phosphates you release energy, and it becomes adenosine diphosphate. Adding one will store energy in it. Therefore ATP and ADP provide energy to help start processes in cell respiration by providing energy. Same with photosynthesis. ATP releases a phosphate group in order to help carry out some of the parts of photosynthesis.

What are the raw materials of photosynthesis and its role?

The raw materials of photosynthesis are water, carbon dioxide, sunlight and chlorophyll.

The main aim of photosynthesis is to form glucose, which is used by the plants to use as food and for storage in the form of starch. Hence, water is used as a source of hydrogen in the formation of a glucose molecule.

Carbon dioxide acts as a source of carbon and oxygen for the formation of glucose molecules.

Sunlight is used as a source of energy to conduct the process of photosysthesis.

Chlorophyll are the green pigments present in the plants that impart the plants with a green color. Chlorophyll molecules are excited in the presence of light and liberate electrons, that split water into hydrogen and oxygen. The hydrogen combines with carbon dioxide through various complex processes to form glucose, and the oxygen is liberated out into the atmosphere.

When does vaporization take place?

Vaporization takes place when a liquid is heated to its boiling point and changes into a gas. This process occurs when the molecules in the liquid have enough kinetic energy to overcome the intermolecular forces holding them together.

What is light harvesting?

light harvesting is a set of photosynthetic pigment molecules that absorb light and channel the energy to the photosynthetic reaction centre, where the light reactions of photosynthesis occur.

How do you make Homemade plant food?

To make homemade plant food, you can mix compost, coffee grounds, eggshells, or banana peels with water to create a nutrient-rich liquid fertilizer. Another option is to steep seaweed or nettles in water to make a nutrient-packed plant tonic. Remember to dilute these homemade plant foods with water before using them on your plants.

Location where photosynthesis occurs?

Photosynthesis takes place in the cells of green plants.

The process of photosynthesis is carried out in the chloroplasts. More specifically, the light reaction takes place in the thylakoid membrane, while the dark reaction (light independent) takes place in the stroma.

What kind of light drives photosynthesis?

Plants primarily use visible light, with red and blue wavelengths being the most effective for driving photosynthesis. Green light is less efficient because it is reflected by chlorophyll.

What are the five major branches of chemistry?

there are five branches: inorganic, organic, analytical, physical, and biochemistry. they could be further broken down into sub-branches such as organometallic chemistry, physical organic chemistry, electroanalytical chemistry, and so on and so forth.

What are stacks of thylakoids called?

granum are stacks of thylakoids.

grana are several stacks of thylakoids. :)

Why is photosynthesis necessary of plants?

Photosynthesis is necessary for plants because it is the process by which they convert sunlight, water, and carbon dioxide into glucose (sugar) and oxygen. Glucose is used by the plant as energy for growth and other metabolic processes, while oxygen is released into the atmosphere for other organisms, including humans, to breathe. Without photosynthesis, plants would not be able to produce their own food and sustain themselves.

How do your cells get oxygen glucose and the raw materials that they need to respire?

Cells get oxygen through the bloodstream, where red blood cells carry oxygen from the lungs to the cells. Glucose and other nutrients are also transported through the bloodstream after being broken down from the food we eat during digestion. This process ensures that cells have the necessary raw materials to undergo cellular respiration and produce energy.

What is the relationship between photosynthesis and respiration?

In photosynthesis plants use the suns energy as light to give carbon dioxide and water into glucose's. In cellular respiration glucose is ultimately broken down to slow down and or stop carbon dioxide or water, and the energy from this is ATP energy
Photosynthesis stores energy in complex organic molecules, while respiration releases it.
